Profiling of aggressive vs benign pancreatic infiltrates in the BDC2.5 Tg model of Type I diabetes

ABSTRACT: This study was performed to understand what controls the aggressivity of the pancreatic infiltrate during type-I diabetes development. We used the BDC2.5 transgenic mouse model. Samples were obtained at the age of onset of insultis. Depending on their genetic background, mice transgenic for the BDC2.5 T cell receptor present very different forms of insulitis. The NOD genetic background leads to a benign insulitis whereas the C57Bl/6-H2g7/g7 leads to an aggressive insulitis. We first studied how antigen-specific T cells are affected by these differences by obtaining the transcriptional profiles of BDC2.5 T cells from pancreas and pancreatic lymph nodes. We also compared the gene expression profiles of the entire leukocyte population present in the pancreatic lesion. Keywords: other

NOD.scid, NOD, BDC2.5/NOD and BDC2.5/NOD.scid mice

Project description:Total pancreatic RNA was isolated from 3 week old NOD.scid, NOD, BDC2.5/NOD and BDC2.5/NOD.scid animals by GITC method. Targets were produced using standard Affymetrix procedures from about 10ug total RNA. The data from NOD.scid, NOD, BDC2.5/NOD and BDC2.5/NOD.scid Affymetrix MGU74Av2 cel files was converted into Robust Multi Array (RMA) text file for analysis using GeneSpring 6.1 Keywords: other

Gene expression profiling of BDC2.5 CD4T cells isolated from NOD mice after in vivo antigen stimulation with either DEC205+ or DCIR2+ DCs.

Project description:We identified DCIR2+DCs but not DEC205+DCs as able to induce peripheral T cell tolerance in pre-diabetic autoimmune NOD mice. To determine what distinct genetic programs are elicited in the auto-reactive CD4 T cells early after stimulation by these two DC subsets, we utilized adoptive transfer of BDC2.5 CD4 T cells into NOD mice, which were then given chimeric antibody to deliver the beta-cell specific antigen to either DCIR2+DCs or DEC205+DCs, leading to BDC2.5 CD4 T cell specific stimulation in vivo. The analysis shows that the negative transcriptional factor Zbtb32 (ROG) is up-regulated more in BDC2.5 CD4 T cells after stimulated with a antigen via DCIR2+DCs presentation, compared with DEC205+DCs, suggesting the involvement of Zbtb32 in DCIR2+DCs-mediated auto-reactive T cell tolerance in disease ongoing NOD mice. The BDC2.5 CD4 T cells after 14 hour of injection with a 100 ng of anti-DCIR2-BDC, anti-DEC205-BDC antibody, or PBS as a control to NOD mice, were sorted by BD FACSAria and their expression profile was analyzed using Affymetrix chips. NOD mice with transferred BDC2.5 T cell were injected with 100 ng of anti-DCIR2-BDC (NOD_DCIR2-BDC), anti-DEC205-BDC antibody (NOD_DEC-BDC), or PBS (NOD_PBS) as a control. After 14 hours, BDC2.5 CD4 T cells were sorted by BD FACSAria and their expression profile was analyzed using Affymetrix microarray chips. Each sample has a biological duplicate. Raw data were preprocessed with the RMA algorithm in Partek, and averaged expression values were used for analysis.
